Where's the best place to sell domain names??

I have recently started buying domain names witht he hope of selling them on for a profit.
I have a few decent one word .com, .net and .org domains, as well as some decent other extensions, such as karma.cc and graffiti.com.co

Where is the best place to sell these??

I have listed a couple on Flippa however at $19 (without paying any extra listing fees) I find this a bit steep and also feel that they are not getting much coverage for the cost.

Sedo.com for sure - free to list all your domains, pay a commission upon sale.
Afternic.com - There is a small annual fee, but the buyers here are serious.
Forums - NamePros.com and DNforum.com. Expect to sell for a fraction of the retail price, as you're selling to domainers and resellers.

I suggest you to try Flippa, many sellers are satisfied with the price as well as customers too. Your site will not be overpriced and in the same time it will not be sold for a cheap price. It always depends on the quality of the domain name too (back links, keywords on the domain name, extension etc.)

Is anyone familiar with selling sites and domains on Flippa? My partners and I have several networks of sites of which we would like to sell off individually. We are looking for someone familiar with selling websites on Flippa and handle the transactions through Escrow.

Commissions would be around 10-15% of the sale after expenses and expect most sites to sell in the 5-figure range because they are well established with traffic and/or revenue. Please PM me if anyone is interested and capable.

If you go down this road be aware of the fact that you will have to hand over your site FTP login details to the person posting the sites for sale so that they can meet the site submission parameters that Flippa require.

Domains are an easier proposition, but they don't sell as well as sites do on Flippa in my experience.
